Right but:
- The world of BGP peers is a rarified one, there are, what, <20k
ASes out there? Nearly all are medium sized enterprises, institutions
or organisations or bigger.
- With BGP's peer-to-peer trust relationships, prefixes get hijacked,
rogue ASes collude with spammers.
So, despite the small number of players, it still doesnt work, and
people are working on adding stronger forms of verification of
announcements to to BGP.
And you want to try scale this to the millions and millions of SMTP
hosts? :)
